Using dry ice safely

Dry ice is -109º F, which is cold enough to freeze skin cells, causing an injury similar to a burn. Never allow dry ice to come in contact with skin. Always handle dry ice with protective gloves or a towel.

Ventilation

Dry ice converts to carbon dioxide gas so if left in a confined space it will displace oxygen and present a suffocation hazard. If dry ice has been in a confined space (e.g. a closed car or room) for more than 10 minutes, open the doors and windows before entering or you could experience difficulty breathing. Leave the area immediately if you start to breathe quickly or have any difficulty breathing.

Storage

Do not store dry ice in a container that is completely airtight. As the dry ice sublimates to carbon dioxide gas, it will cause an airtight container to expand and possibly explode.
